How an electric grass trimmer works

What’s the best electric grass trimmer?

Most farmers require garden tools to be not only reliable and efficient, but also safe for health and the environment. Basically, this is what caused the emergence of electric trimmers as analogues to the more familiar petrol mowers. Unlike gasoline models, electric grass trimmers have low noise and vibration levels, less weight, and most importantly, the ability to mow lawns more accurately in very confined spaces. This makes it possible to use them to care for small flowerbeds, as well as greenhouses and other enclosed outbuildings.

Many beginning gardeners ask this question. To give an unambiguous answer to it is not easy, given that, as a lawnmower, and the trimmer for the grass electric, have their own advantages and disadvantages.

To determine which garden tool is still the best, you need to sort out a number of important factors.

  • The area of the plot. when buying an electric garden tool, you should remember that the area in which it can be used is severely limited by the length of its regular cable. In most cases, electric models come complete with cables that are no longer than 20 meters. If the area is larger, then to work on it with a trimmer for dacha will need to use an extension cord, which in most cases brings its own inconvenience. If there is no such a possibility, you can buy a garden tool equipped with a battery. This grass trimmer also has one disadvantage. it will take at least 3 hours to fully charge its battery. From all this you can conclude that electric grass trimmers are best suited for the care of small yards and yard areas. If the area of the plot is more than 5 acres, then for comfortable work on it you will have to buy a brushcutter;
  • The type of wild vegetation to be dealt with influences the choice of garden tool. Standard electric mower, 1-1,5 kW, is initially designed to cut weeds with a stem thickness not exceeding 2 mm. When using it to cut thicker shrubs, the tool’s motor will work under increased loads, which can lead to a difficult breakdown of the model. So, to be on the safe side, for tall grass and uneven areas, it’s best to use gasoline grass mowers;
  • Easy operation and maintenance. an electric grasshopper is the best choice here. It is much easier to work with, because the operator will not have to pull the starter handle every time and adjust the throttle position. Switching the tool on and off is done by simple push of a button on the housing. In addition, the electric lawn trimmer is unpretentious in maintenance. It does not need to use oil for the motor and adjust the carburetor;
  • weight and dimensions are another plus in the list of advantages of an electric tool. Standard hand-held electric mower differs from gasoline-powered tools by its modest weight and small size. This greatly simplifies its operation and makes it possible to use the grass trimmer to work in conditions of very limited space;
  • noise. this characteristic affects the convenience in the daily operation of the garden tool. Modern gardeners need a comfortable model that does not make noise or vibrate. In this case, a lightweight electric grass trimmer will be the best option;
  • price. one of the most important parameters, which almost all gardeners pay attention to. As a rule, a powerful electric mower costs an order of magnitude cheaper than its gasoline counterpart. Due to this, electric garden tools are now in high demand among owners of country properties.

To summarize, el. trimmers for grass is suitable for use in small areas with low-growing wild vegetation, as well as for work in greenhouses and decorative flower beds. For the care of large territories, the area of which exceeds 10 acres, it is best to buy a more powerful gasoline mower.

What is the best electric trimmer for grass. tips for beginners

Choose an electric grass trimmer for the grass will help to study a number of its most important parameters.

  • power. on this factor, mainly depends on the range of use of the tool. Grass trimmers with power from 450 to 1000 watts are suitable for cutting small lawns, the area of not more than 2 acres. In order to fight weeds in areas with a larger area, you will need to buy a more reliable tool with more power;
  • motor protection. for safer work with electric mowers, manufacturers of garden equipment equip it with multi-level protection, which prevents the breakdown of the tool in case of a short circuit, as well as moisture and dust getting into the motor;
  • type of drive shaft. electric tools can be equipped with both rigid and flexible drive shafts. The first option is considered more preferable due to its reliability and endurance;
  • the width of coverage when mowing. most household models are capable of mowing an area with a diameter of 25 cm at a time. powerful professional grass mower covers a much larger area. from 30 to 40 cm;
  • The possibility of combining cutting headsets. this factor depends on the power of the model. If the power is 450-900 watts, the manufacturer advises to use only a plastic spool with a fishing line to work with a mower. If the power is higher, the grass trimmer can be equipped with plastic or metal cutting blades;
  • free access in the body. in order to simplify the repair of equipment, manufacturers leave in the device of the electric grass trimmer free access to the air filter and other parts of the model. This greatly simplifies scheduled maintenance and makes it possible to replace its worn parts with your own hands.

Having studied these factors, it will be easier for an inexperienced gardener to compare the pros and cons of all models. This will give the opportunity to choose an unmistakable electric scythe for dacha.

Varieties of trimmers with fishing line

There are quite a few of them today, so everyone can make a choice based on their own needs. Cordless grass trimmers with fishing line are designed for people who want to work independently of a power source, they are the most popular. As an example, we can cite:

  • Champion TB400. cordless grass trimmer. It has a telescopic boom, compact size and light weight of just 2.8 kilograms. Provides a limiting clamp, to prevent damage to useful plants;
  • Gardena PowerCut Li-40/30. Professional tool that can handle even wet lawns. Deserving extra attention is the ability to adjust the head to work at an angle in hard-to-reach places.

Gasoline trimmers for grass is more expensive, requiring regular refueling, but it pays off at the expense of high power and the ability to work long hours on the site without ties to the power source:

  • Partner B305 CBS. Despite its light weight, has great power. Gives you the freedom to tidy up your green spaces without harming them by minimizing exhaust emissions. A special grass knife and a TapGo trimmer head operating in semi-automatic mode are used as cutting tools.

Most modern trimmers can be equipped with an optional fishing line head. There are four types of spin trimmer heads:

  • automatic heads automatically feed the thread when the throttle reaches a certain speed;
  • semi-automatic heads advance the string when you push the spindle head to the ground when the throttle is engaged;
  • manual heads require that you turn off the grass trimmer before pulling or unwinding the string to advance it;
  • fixed line heads do not advance the strings. Instead, you use pre-cut lines to replace.

How to properly use a trimmer

A household grass trimmer is the easiest to use, yet very effective tool. It seems to be very easy. plug the tool into the socket and work. But there are still some nuances that you need to know in order for the grass trimmer to work long and productively.

Prepare the area. You need to carefully examine the mowing area and remove all foreign objects, like stones, glass, wire, etc.д. Flew out suddenly from under the line during work, such an object can cause injury.

Adjusting the cutting system. There are low-power grass trimmers that can only work with a fishing line, mowing soft and succulent grass. they do not need a cutting system installed. But some trimmer models, in which the motor has a 1 kW or more capacity, can work with a knife. If there are stubborn weeds or even small bush growth on the site, you need to unscrew the nut of the working mount and install the cutting blade. Then tighten the nut tightly with a wrench.

Before you start. It is very important when working with trimmers wear protective goggles, because even if you have cleaned the area from debris, plant stems and grass can fly into the eyes. The same stems, grass, and branches can also injure your hands, so it is advisable to wear gloves as well. Electric grass trimmer simply plugged in, but the battery trimmer needs to be charged for a few hours before work. If we have a shoulder strap we can hang it on one shoulder, and if we have a backpack strap we can hang it on both shoulders. Grasp the grass trimmer grip comfortably: the D-handle must be gripped firmly in the palm of the hand, and the garden trimmer with a bike handle (U-handle) must be held firmly with both hands. Hold the grass trimmer above the grass, so that the line spool or the blade is parallel to the ground. Start.

How to mow correctly. The cutting mechanism should rotate counterclockwise. Thus, in order to make the cut grass fall on the already mowed area, easily, with simple movements, move the trimmer in front of you, from right to left. To remove the remnants of grass move to the opposite side, from left to right. If the area is flat and large, divide it into imaginary squares and mow by moving around the outside of such a square. If the area is on a slope, you need to start mowing from the bottom of the lawn, going across the field. in one line. Reaching the edge, you need to go back and mow in the same direction, parallel to the edge. If there are many trees on the plot, mow only with a fishing line, otherwise you can cut the tree trunk with a knife. In such a garden, it is best to mow along the perimeter, going around the tree in a circle.

Technical characteristics of gardening equipment

Electric grass trimmer allows for regular maintenance of the garden and homestead plot. Its main advantage is its maneuverability. It is able to reach any hard-to-reach place.

Experienced gardeners do not recommend using this device for the care of a large lawn. The fact that in the process of mowing tall grass, sharp drops can be formed, which negatively affect the appearance of the green carpet.

What to consider when choosing a product? The main technical characteristics include:

The power of the device. Depending on the type of model, it ranges from 250 to 1500 watts.

Type of power. The most popular are battery-powered trimmers. They are charged from the mains and can work for up to 6 hours without recharging.

Devices with an electric cord, has higher power.

The shape of the boom. Depending on the model, they come in curved and straight.

Motor placement. It can be located either in the upper part of the tool or in the lower part.

Cutting surface. It is presented in the form of a fishing line or flat blade. Sharp knife allows you to get rid of young shoots of bushes and trees. line trimmers are designed for cutting soft grass.

How to choose a mower by type of power?

The model should be chosen according to the size of the garden plot. If it is about 10 acres, a compact model with minimal weight will be the best solution. It usually has low power, which is enough for permanent mowing of lawn grass and weeds.

If the dacha plot is large, more powerful devices will be preferred here. They allow you to transform the surrounding area in a short period of time.

As for the shape of the rod, then each consumer selects the model based on its ease of use. Angular trimmers are suitable for a large lawn. Installations with a straight handle can reach hard-to-reach places.

The instructions of the electric grass trimmer provide detailed recommendations on the use of this unit. You should not make any sudden movements while cutting the grass.

The main most common faults of electrocosms and trimmers

The spool (bobbin) has run out of line for the trimmer. Most spools have semi-automatic line feed, with a light knock on the ground, the line for the trimmer is fed to the output. If the line is not fed to the trimmer, you need to remove and disassemble the spool. Spool and, if necessary, reel in new fishing line for the trimmer.

The line for the trimmer may be too long, because the blade that is recognized for cutting extra length of line is blunted, or it does not exist at all. The length of the line should be slightly less than the diameter of the guard.

A heavy hum and vibration during engine operation may indicate that the bearings need lubrication or have used up their resource. Also the body of the spool with the line (bobbin) may be cracked, it and the place of its attachment should be inspected for cracks and damage.

Most electric motors in mowers and trimmers are collector-based and do not have a speed regulator, with a reduction in line voltage. RPMs and horsepower decrease. Spool of fishing line may be wound incorrectly. RPMs may be hindered by a stuck rod or rope wrapped around the shaft, inspect design. If the mower is working properly, the shaft should turn easily and without the slightest effort, even after using your finger.

The motor does not turn? Please check if the plug is powered, if everything is ok, the machine needs to be disassembled. If no obvious damage is noticeable, then start a sequential testing of the electrical circuits of the device.

Using a multimeter (tester), firstly test the power cord, the fuse, if there is one, and the button. If the button does not give out when turned on it should be replaced or if it is demountable open and clean the burned contacts.

The cord may be broken, in this case the engine may start irregularly. The fact that the motor may be defective if the button is turned on, the motor terminals are supplied with voltage of 220 volts, but it does not rotate.

Some motors are equipped with a thermal fuse, which is built into the motor housing and triggered from its overheating, or just out of service. An operational thermal fuse, when the motor cools down, should restore its operation.

How to assemble correctly grass trimmer. Step by step Instruction PHOTO VIDEO

Garden trimmers for grass are similar in design. Detailed instructions for one model will help to understand the intricacies of installation of analogues. Consider the basic steps of assembling the electric trimmer on the example of the FUBAG FET 1200R.

Before we proceed, let’s understand what we have on our hands after purchase. The tool is sold in disassembled form:

Also included are a shoulder strap, a three-bladed blade, and a tool set.

Bar shape

Straight grass trimmer bar indicates its great power, reliability in operation and durability. In this composition, the torque from the engine is transmitted to the grass trimmer head by means of a steel shaft. Consequently, this connection has a very high level of efficiency and durability.

In trimmers equipped with a curved rod, the rotation of the cutting tool (usually a spool of fishing line) is transmitted through a thin metal cable. This method of torque transmission is considered less reliable. But what can be said unambiguously, models with a curved bar have much less power and are used in small areas with rather soft grass.

How to service the lawnmower

Lawn mower. a popular technique for mowing unwanted vegetation in plots, gardens and parks. But like any other equipment, lawn mowers require constant care, maintenance and sometimes minor repairs, which can be done yourself. And if you bought not an electric, but a lawn mower, what kind of gasoline should be poured into the fuel tank? In this article we will consider the basic principles of maintenance of gasoline mowers and tips, what to do with the unit before each start-up, how to prepare the fuel mixture and tell some secrets of mowing the grass from experienced gardeners.

Maintenance of the lawnmower

Here you will find information on how to properly care for all parts of the equipment, how to adjust, how to disassemble and with what and how to lubricate the lawnmower (moving parts).

Engine. Keep the air filter clean and free of oil and grease. Fuel filter should be checked at least weekly and replaced in time if defective. Muffler and plugs must be decalcified at regular intervals (as they become soiled). Check all screws and nuts for tightness before every operation.

The bevel gear must be cleaned of dust and dirt as often as necessary, since this prevents efficient cooling and then lubricated with any type of gear lubricant, e.g. STIHL.

Trimmer head with fishing line. The mowing head must be cleaned after every use of the grass trimmer and replaced in good time if it is found to be warped or cracked. Only special cord (trimmer line) for trimmers should be used, no ropes or wire! The diameter of the fishing line should be as stated for the specific model. Make sure the filament is wound tightly but without crossing the threads.

Cutting attachment (disc or blade). Metalwork must be sharpened (special templates and files exist for this purpose) at a special angle. On double sided models it is advisable to turn them over from time to time to ensure even wear. Blunt or improperly sharpened discs and blades will overload the engine and shorten the working life.

The blade guard should always be on when mowing. They protect the operator from flying grass and stones from under the cutting equipment and also reduce the load on the engine. After work thoroughly clean the inner and outer surface of the housing with a jet of water or a soft cloth, taking care not to scratch the surface.

How to adjust the lawnmower (carburettor)

Correct adjustment is essential for successful future operation.

Beginners sometimes do not know how important this process is for benzocos and benzotrimmer, and miss it or simply do not know how to adjust the lawnmower carburetor, believing that the factory settings are quite enough. However, this is not the case. Inspect all mechanisms and adjust carburetor regularly.

Important information and tips for adjusting the gasoline carburetor on your chain saw:

  • There are 3 screws in the carburetor: left (H), lower (T) and right (L). To get to the screws, you need to know how to disassemble the lawnmower, and more specifically, how to get to the carburetor. This information should be specified in the product data sheet.
  • The lower screw (T) is responsible for idling, the right screw (L) for the amount of fuel entering the combustion chamber at low rpm, and the left screw (H) is responsible for fuel entering at high rpm.
  • Turn on the carburetor at idle speed. Properly tuned, it runs evenly when the motor is hot and cold, at lower and higher rpm. If something goes wrong, you need to turn the lower screw (T).
  • Adjust the fuel intake at low speeds by turning the right screw (L) a quarter turn counterclockwise.
  • Adjust the carburetor at high revs as follows: open the throttle and press the maximum throttle. Turn the left adjusting screw (H) clockwise until the speed is lower. Then turn the screw counterclockwise until the motor does not run smoothly. Then slowly turn the screw back clockwise until you hear the motor run smoothly and evenly.
  • The spark plug also serves as an indicator of proper carburetor adjustment. If it malfunctions, the spark plug has soot on it, but if it is adjusted correctly, the working part of the plug stays clean.

This is the most universal algorithm on how to adjust the carburetor on a gasoline mower. Individual adjustment depends on the model configuration of your machine.

Preparing the fuel mixture for the lawnmower

Many first-time users ask what kind of gas to put in their lawnmower? The passport of each lawnmower should specify what fuel can be used with this particular model. But gasoline alone will not power a lawnmower, you need a fuel mix of the right proportions. What is in the fuel for chain saws and gasoline-powered trimmers??

Gasoline. any high-octane (AI-92 and 95 and a density of 750 to 770 kg per cu.м). Gasoline must be fresh and clean, which means

Oil. you can use oil for two-stroke engines (with speed of 10000-15000 rpm) of high quality, for example, STIHL, PATRIOT, Husqvarna, Bigmaster will also do.

Fuel mixture proportions. if not stated differently in the product data sheet, you can use this scheme: 1:50 (2 percent oil from 100 percent gasoline) or 20:1000 ml.

One example of preparation of fuel mixture (in proportion of 10 ml per 0.5 liter): pour 0.5 liter of gasoline in a transparent container, gently add 10 ml of oil (you can use a medical syringe without needle), mix and pour the rest of the gasoline in the end. Stir the resulting mixture thoroughly. If the quality of the gasoline is low, you can increase the oil volume to 25 ml.

Our article is of an introductory nature, so if you have a lawnmower, how to dilute gasoline (the correct proportions of gasoline and oil) should be specified in the technical passport of the model.

Grass trimmers for beard and mustache

Probably the most interesting in operation are devices for the mustache and beard. Modeling a mustache and beard requires some uncomplicated skills and a little time.

If removing hair in the nose and ears or trimming eyebrows is not particularly difficult, to contour a symmetrical beard requires mastering the sequence of work and mastery of movements.

Modern models give you the opportunity to create any kind of beard: the effect of five-hour facial hair, three-day stubble, espagnolo, Hollywood, skipper beard and other types of beard and mustache. The result depends on your imagination, the shape of your face and facial hair.

Before you start, it is necessary to clean the hair from sebum and other dirt. To do this, the beard is shampooed and a conditioner can be used. Dry hair is combed in the direction of hair growth, from top to bottom, to smooth out all hairs. These simple procedures will ensure an even result.

When modeling a beard and mustache, you must first decide on the optimum beard length. If the beard is very long you can start by shortening it with scissors, and then move on to modeling directly with the tool. The beard should be cleaned starting on one side of the face, going from one ear to the other.

The device should first create an even surface of the beard, then, using the appropriate nozzles:
